Abstract: The invention includes a floor reinforcement structure for vehicle body providing rigidity to an area around a main and rear floor joint; improving vehicle-body rigidity and rigidity against floor shaking and associated vehicle interior noise; and improving vehicle running stability. A floor reinforcement structure includes: a main floor; rear floor; side sill; a floor tunnel with a hat-like cross-section protruding from the floor and located medially in the main floor in the vehicle width direction and extending in a front-and-rear direction; and a vertical wall at the front of the rear floor extending in a vehicle vertical direction. The vertical wall is continuous with no steps The height of a top face thereof is larger than twice the height of a top face of the side sill, which is more than twice the height of a top face of a rear end portion of the floor tunnel.

Abstract: A vehicle body rear floor structure characterized as follows is provided. The front end of a rear floor panel in a vehicle longitudinal direction includes a front wall extending between a pair of side sills. The front wall forms an arc whose central part in a vehicle width direction projects upward from the floor. The front wall lower end is joined to a rear end of a main floor panel. A cross member forms an arc whose central part in the vehicle width direction projects upward from the floor, and extends along the front wall with the central part of the cross member in the vehicle width direction placed on a floor tunnel. The cross member ends, in the vehicle width direction, are joined to the side sills and main floor panel. The cross member central part in the vehicle width direction is joined to the floor tunnel.

Abstract: Structure of a vehicle body rear part in which a back door opening section around which a closed cross-sectional structure is provided wherein the vehicle body rear part includes rear lamp house panels, a back panel section and a back door opening section arranged to incline obliquely such that a lower part is located further toward a vehicle back than an upper part. In the structure, a tail end member extending along a vehicle width direction is coupled to lower side corner portions of the closed cross-sectional structure located on both the left and right sides of the back door opening section, swelling sections extending further outward than the lower side corner portions of the closed cross-sectional structure are provided on both the left and right sides of the tail end member, and the swelling sections are joined to the rear lamp house panels and the back panel section.

Abstract: Structure for lower vehicle body of vehicle front part is disclosed herein. In some embodiments, structure includes suspension frame fastened to connection parts of front side members and floor side members; dash side members extend from fastening parts obliquely rearward and outward in vehicle width direction; outer end parts of dash side members connected to front end parts of side sills; front surfaces of lower parts of side outer panels arranged ahead of front end parts of side sills; dash side outer panels, side outer panels, and dash side inner panels connected together by flanges extending in vehicle up-down direction of front end part of each thereof, at positions of front surfaces of lower parts of side outer panels, side outer panels formed into an inclined surface inclined obliquely downward toward vehicle rear in side view and inclined obliquely rearward toward outside of vehicle in top view.
